I have an eMachine 3110 & when I power it on, the fans all spin & the CPU fan spins spins as well. I have replaced the motherboard & CPU & it does the same thing. I also put a spare power suppy in it with no luck. Now I am down to replacing the RAM. I took the RAM out & though it would produce some type of beep cope it does not. Also, the weird part of it, I can taake the RAM out & leave it off for a few minutes then place it back in, sometimes the computer will come on & went to the desktop & another time I could not get past the BIOS.....Now, when I tuen it on, the CPU fan spins at a loud very fast rate....what are your thoughts on this???
